I attended Barnett's 2 week course in colorado spring, and we covered wheel building for about a day and a half of the course. They have taken all the guess work out of it. they have a formula that they have figured out for wheelbuilding. Provided you start out with a rim that is straight, and good spokes that are the right length, it is really easy to get a good straight, perfectly tensioned wheel. Once you bring the wheel up to tensioin, you take some readings with your tension tool and plug it into an equation with a multiplier they have figured out and it actually tells you how many turns on the spoke wrench to get it right. No if I could tell you easily how to do this I would, but there is a guide to follow, and they may even have it copyrighted I'm not sure. But if you are close to them I would recommend taking their wheelbuilding course, it is great. Oh and the riding there is awesome, makes a nice trip destination.
